Fault Root Cause Identification Method, Apparatus, and Device

2. The method according to claim 1, wherein the first failure flow, the first target success flow, the plurality of first success flows, the plurality of second failure flows, the second target success flow related to each of the second failure flows, and the plurality of second success flows are all transmission control protocol (TCP) flows, internet protocol (IP) flows, or user datagram protocol (UDP) flows.

7. The method according to claim 5, wherein the initial coefficient sets are randomly selected by using an e-greedy algorithm.

8. The method according to claim 1, wherein the target fault root cause comprises IP offline, application offline, a security device layer exception, a routing device layer exception, a network port error, or application overload.

11. The apparatus according to claim 10, wherein the first failure flow, the first target success flow, the plurality of first success flows, the plurality of second failure flows, the second target success flow related to each of the second failure flows, and the plurality of second success flows are all transmission control protocol (TCP) flows, internet protocol (IP) flows, or user datagram protocol (UDP) flows.

16. The apparatus according to claim 14, wherein the initial coefficient sets are randomly selected by using an e-greedy algorithm.

17. The apparatus according to claim 10, wherein the target fault root cause comprises IP offline, application offline, a security device layer exception, a routing device layer exception, a network port error, or application overload.
